To all whom it may concern: 4

Be it known that I, JosEPH Vownns, of Milford,- in the county of Oakland, and State of 'Micliig'am have invented anew and useful Improvement in Cultivators; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being; had to the annexed drawings, making part of this specifi This invention consists -f First, in the construction of the reversible "-mou1d Secondly, in the device by which the orlowered; g j p f r Thirdly, in the construction of the lever which is attached to the axle," and in the means for attaching it thereto. I v

' Fourthly, in the general arrangement of the parts of which the cultivator is composed. I

Figure 1, sheet 1, is aperspective view of the machine, showing its general arrangement, as well as the device for raising and lowering the same upon its'axle, and the reversible mould-board attached to its'hangers.

Figure 2, sheet 2, is a sectional side elevation, showing the device for raising the machine, or for lowering the same, so as to give the plows the required adjustment, or to remove them from the earth altogether, so as to facilitate the-transportation of the machine fi'orn one place to another. Figure 3 is a rear cross-section, showing the bent axle, the mechanism for raising and lowering the frame 'and plows or teeth, and a rear-end view of the mouldboard, with the means of attaching it to the frame: Figure 4 is a view of the reversible toothor plow, showing the manner of attaching the same to its hanger. Figure 5 is a view of the lever which is attached to the main shalt, for raising or lowering the frame-work of the machine to which the teeth or plows are suspended, by which means the depth of the furrow is regulated, and it also shows the sector, by which said lever is secured in any desired position, and the means of attachingsaid lever to said shaft.

Figure 6 is a side view of a portion of the tongue,

and of the sub-tongue to which it is attached, and it also shows an end view of the wedge or devicefor raising or lowering the forward end of the tongue, as circumstances may require,

The same letters indicatethe same parts in all the figures. y

A A are the wheels, which are secured to the axle in the usual manner.

B is the axle, which is constructed as shown clearly in fig. 3 of the drawings, the object being to attach the frame-work of the machine to the straight portion of the axle, within the ofisets, so that it may be raised up, as shown in said figure, to such an extent as to permit the machine to be 'drawn .from one place to another without permitting the teeth to come in contact with the earth, or it may be turned down, by.

- so'that when i means of the lever C, so as to assume the position shown in fig. 2, and so as to allow the teeth to cute the eartlinto any reqnireddepth. r

G is the lever, which is attached to the axle for the purpose above described. Said leveris of peculiar con I struction, theQcavitya in its lever-end being lsemicir cular in form, and having a slight projection; castpuponj it tojeuter a recess madein the-shaft or axleB, to preventlthe possibility (streaming to move the'axlewhen 'itisniovedlji y a TotheQlower' end of this'lever is attachedcap, 1 m a nem amna n heo e b v eu 1 p aced iinponae.lev hstwqv l melamine-taxman sle: inner-Tendofith ta win rest upon-the lever, whilst their outer ends will besome distance. apart, so that'as the bolt ais. passed through them, and the nut secured down, the two willbe permanently attached tothe axle; r -D is the sector, which; is secured to the frame-work of themachine, by the side of the lever,- and has-aseries of holes drilled or cast-in it to receive and hold a pin,whichis attached to a handle, which is attached to the outer end of the lever G, and is pivoted thereto in such a manner that when held in the position shown in'fig. 3,' the"lever will'be'retaiued in its position thereby, but'when it is desired to change the position of the lever with reference to the sector, for the purpose of raisingor lowering the teeth or plows, the" upper end of the handle is pressed inwards, and the pin is thus withdrawn from its seat in the sector, and the lever can be moved to any desired position, when, by releasing the hold upon the handle, a spring, screwed between it and the lever, will return the pin to its position within the sector, and thus the lever willbe secured in its new position.

-. E E E E are the timbers composing the frame. of

held together at their ends or points of contact by bolts and-nuts in the usual manner. The rear one of these timbers is considerably longer than the front one, and

is for the purpose of fastening thereto the hangers, which carry-upon their upper ends handles, by which the machine is guided with reference to the rows of the crop."

F is. asub+tongue or timber, extending from the rear cross-timber E to and some distance beyond the front one, the object being to attach to the projecting portion the adjustable-tongue. This sub-tongue also carries one of the hangers K.

G is the tongue of the machine, and it is attached to thev sub-tongue in such a manner that its forward end may be raised, or lowered, as circumstances may require, independent of the particular position of the frame of the machine.

The device for accomplishing the above-named resuit consists of a wedge-shaped picoeof metal, having flanges upon its ends, placed between the tongue'and the sub-tongue, so that by'unscrewing the not of the bolt which confines the two together, and moving the above-described wedge forward, the outer end of the tongue will be raised, and vice cersa.

2 H Hare the two rear hangers, which are provided with handles, as above described, and which are attached to the rear cross-beam E, at such a distance apart that the tooth or plow placed thereon shall be nearly or quite in the rear of the wheels, and that the furrows turned therby shall obliterate the track made by such wheel.

I I are braces leading fromrthe hangers H and K to the main frame, for the purpose of supporting'said hangers.

K K are hangers, attached to the sides as longitudinal portions of the frame, and they are so arranged as to occupy a position transversely between the two which are attached to the rear beams, and, when furnished with the reversible mould-board M; as shown; and when the other teeth'with their hangers are removed, as they may be at any time, they may be used conveniently and advantageously for what is termed billing up the crop.

L L are the teeth or mould-boards, which are bolted to thelower ends of the hangers, as above described, vand which are believed to be of novel construction,

said novelty consisting in their being cut straight, or nearly so, upon one of their sides, whilst the other is cut in the form of a circle, thus forming, when bent to the proper form, a mould-board, which, when worn-out upon one end, may be readily reversed,-by loosening the bolt which secures it to the hanger, and the unworn end be substituted for the worn one.

It will be seen, also, that the above-described rnouldboards may readily be changed at any time for the purpose of turning the furrows in opposite directions.

N is the wedge-piece above described, for changing the position of the forward end of the tongue.

Having thus described my invention,

- What I claim as new, and desire to secure by Let ters Patent, is r 1. 'The mould-board L, constructed substantially as shown and described 2. The combination of the mould-board L with a cultivator.

3. The construction of the wedge N, and its arrangement with reference to the tongue of a cultivator, orfor any equivalent purpose, substantially as shown and described.

4. The arrangement 'of thehangers H H with their 'teeth M M, with reference to the wheels of the machine, substantially as shown and described.

5. The arrangement of the sub-tongue F, frame E, sector D, lever O, hangers H and K, and braces I. substantially as shown and'described. I

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
